This invention is directed to a hand beading tool and particularly to a device to provide a head on aircraft tubing.

Aircraft, and especially larger aircraft, have a good many feet of tubing, especially tubing made of aluminum alloy materials. These tubes are ordinarily joined by suitable nuts. However, it customary to slip the nut over the end of the tube then either flange or head end of the tube. The present beading tool has been doveloped to facilitate this beading operation wherever a bead in tubing is required.

An object of this invention is to provide a suit" able beading tool which can perform the beadn'g: operation without requiring removal of the tubing from installation.

Another object is to provide a bead forming device which has general utility and can be used to place a bead on a tube wherever desired.

Details of the invention are described-in corn nection with the following drawings in which Figure l is a plan view of the beading tool.

Figure 2 is a section on line 2-4! of Figure 1.

Figure 3 is a sectional View on line 3 3 of Figure 1.

Figure 4 is a plan view of the beading tool hous" ing.

The drawings show the beading tool assembly. Beading tool housing 5 as shown in Figure 4, is preferably a circular plate member although. the particular shape is not essential. Housing l provided with rectangular opening t2 having ribs I3 extending for a partial length along the sides of the opening for a purpose later described.

Bead roller block H9 is provided with grooves along its side edges correspond ng in shape to that of ribs i3. Block it is inserted in open ng it? and is of such size that with slight movement in open ing 12 the grooves engage ribs it as shown in Fig" ure 3. Ribs are of a length which will permit in sertion of block. es in opening l2.

Movement of block so within opening 22 results by operation of block feed screw which extends through a threaded bore in housing 5 is seated in an ali ned socket in block it. Screw l is provided with a ball It at its end which fits into the socket and is locked in place by means of pin l l or in any other suitable manner. As shown in Figure 1, pin it is driven through a suitable perforation in block it! and engages the neck or ball M thereby insuring retention of ball M within block to. Handles b on the opposite end of the screw permits rotation of the screw and results in corresponding movement of block as within open-- ing I2.

Two anvil rollers 3 provided with peripheral grooves are rotatably secured to housing I by means of shoulder pins '2. The shoulders on pins 72 permit a slight clearance of the pin head above its corresponding roller so as not to resist roller rotation. Rollers are positioned in contiguous slightly relationship as shown in Figure 3. ular bead member is secured to block In asher 9 maintain pin ii in place. The bead tubular member 5 is spaced above block H) the distance to become aligned with the peheral grooves in rollers 13 as clearly shown in Figure 3. It will be apparent that rotation of screw l forces the bead member 5 into close proxy to the anvil rollers it with the head in member in operative relationship with the peripheral grooves in rollers 3.

operation, the tube to be beaded is placed over head member 5 in telescopic relationship. It will be apparent that this relationship is relative and that the bead member 5 might be inserted within the tube to be headed where the beading is to be performed at the tube installation. Bead member 5 is then forced into cooperative relationship with anvil rollers 23 by rotation of screw l and Worked around the periphery of the tube thereby forming a bead.

Spacing and size of bead is determined by propor selection of beading member and anvil rollers. Change of bead member makes it possible to accommodate tubing as small as inch in diameter.

Even though intended to apply a bead on tubing in aircraft installations, it will be apparent that the present tool can be used on any flexible sheet tubing wherever desired. In fact one could readily telescope the tube over one of the anvil rollers thereby forming a concave bead instead of the convex bead formed when the tube telescopes bead member 5.

The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.

What is claimed is:

l. A beading tool comprising a housing plate provided with an opening therein, a block slidably mounted said opening, a pair of grooved anvil rs mounted on said housing in contiguous relationship and symmetrically disposed with respect to said opening, said rollers extending laterally and unobstructedly from the face of the housing for the reception of work to be headed,

a bead member mounted on said block, and means for urging said bead member into operative relationship with respect to said anvil rollers.

2. A beading tool comprising a housing plate, a rectangular opening in said plates, guide ribs along the sides of said opening, a block slidable on said guide ribs, a grooved anvil roller mounted on opposite sides of said housing plate in contigu ous relationship to each other, said rollers eXtending laterally and unobstructedly from the face of the housing for the reception of Work; to be headed, a bead forming member mounted on said block, and means for urging said block and bead The following references are of record in the file of this patent:
